INDIANA, Pa. — Prosecutors are considering an appeal of a judge’s decision to dismiss charges against an Indiana University of Pennsylvania student accused of the strangulation death of a fraternity brother.

Indiana Borough police accused 20-year-old Brady DiStefano of choking 20-year-old Caleb Zweig of Rockville, Maryland, during the February brawl. Zweig later died.

Defense attorney Thomas Dickey said pathologists didn’t find medical evidence to support strangulation and the ruling of asphyxiation.

Judge William Martin dismissed homicide and aggravated assault charges, saying a forensic pathologist acknowledged a lack of physical evidence supporting the strangulation finding.

District Attorney Patrick Dougherty has said DiStefano was seen with his hands around Zweig’s neck and “There’s no other reason to support why this young man is dead.” The district attorney’s office said Thursday an appeal was being considered.
